If you follow these insider tips, your photos will look like you had the place to yourself at the popular tourist attractions.

Vatican Museums: Vatican City

The Vatican draws more than five million people each year, and queues can reach four hours during peak season. Christie Hudson, senior communications manager at Expedia, recommends, choosing a skip­the­line tour. "This not only lets you avoid the ticket counter, but also includes the use of a private partner entrance." Extra time to visit the Sistine Chapel? Yes!

Bamboo Forest: Kyoto, Japan

Bamboo Forest is the most worthy sight in Kyoto. If you're longing to enjoy the pathways and take pictures in total quietness, Kyoto Arashiyama Travel Guide recommends hitting the famous Bamboo Grove Path as early in the morning as possible—think 7 a．m. if you're up for it. Don't miss these hidden treasures you can only witness in Japan.

Chichen Itza: Yucatán, Mexico

Home to E1 Castillo and the Temple of the Warriors, Chichen Itza is a must­see. Want to beat the rush? Schedule an early tour that takes place before a site opens to the public. Led by an archaeologist guide, it's full of fascinating insights and facts—without tons of pack­wearing tourists.

Louvre Museum: Paris, France

The Louvre is one of the most popular museums on the planet. If waiting around in line to get in isn't the way you prefer to spend your time in Paris, consider purchasing a reserved ticket. This will give you entry to the pyramid within a half­hour window. The Louvre is also open until 9：45 p．m. on Wednesdays and Fridays, if you're up for some late­night art visits.

The next time you find an excuse to abandon your ambition, think of Chris Nikic. On November 7, 2020, 21­year­old Chris Nikic made history as the first person with Down Syndrome to attempt and complete an_Ironman. Organized by the World Triathlon Corporation, it requires athletes to swim 2.4 miles, bike 112 miles, and run a full 26.2­mile marathon—in under 17 hours!

The event, which took place in Panama City, Florida, began early in the morning with a two­lap swim in the Gulf of Mexico. Chris, who was tied to his coach for safety, completed the course well within 2 hour, 20­minute timelimit.

The 112­mile bike ride, which Chris rode alone, proved a little more challenging. Not accustomed to drinking water while riding, he was forced to make multiple stops. To make matters worse, the young athlete was attacked by an army of red ants whose nest he accidentally stepped on during a break. He also had a bleeding knee after crashing while speeding downhill. Despite these setbacks, Chris managed to complete the lap before the 5：30 pm cut­off time.

The competition's final challenge—a two­lap 26.2­mile run along the waterfront—started smoothly. However, Chris was tired out by the tenth mile. But with encouragement from his coach and cheering bystanders, the youngster somehow managed to cross the finish line in 16 hours, 46 minutes, and 9 seconds—almost 15 minutes under the 17­hour timelimit.

Chris is no stranger to overcoming challenges. Born with two holes in his heart, he underwent surgery at just five months old. He was too weak to walk independently until he was four. Due to his Down Syndrome, every expert his parents spoke to focused on the limitations rather than the possibilities.

To Chris, this race was more than just a finish line and celebration of victory. It's about being an example to other kids and families that face similar barriers.

If you walk through a park in the morning, you'll see a series of beautiful movements performed in a slow, focused manner with deep breathing. While this may be a common sight for many, this practice was recently given remarkable acknowledgment.

On Dec 17, China's tai chi was officially listed on the United Nations Educational, Scientific and Cultural Organization (UNESCO) List of Intangible Cultural Heritage.

Tai chi is "a traditional physical practice characterized by relaxed, circular (环形的) movements that work in harmony with breath regulation and the cultivation of a righteous (正直的) and neutral mind"， noted China Daily. The origins of tai chi can be traced to Wenxian County in Henan Province in the mid­17th century. Now it has spread to more than 150 countries and regions, attracting more than 100 million people to practice.

Tai chi can be practiced any time and anywhere without equipment. It is a practical way for one to further balance, motor control and rhythm of movement. However, for many, it is more than just exercise.

"Tai chi is not just a sport to make people fit, but also contains Chinese culture and philosophy that can make people peaceful，" Yan Shuangjun, a researcher of tai chi, said.

Marleni Calcina from Peru is an example of the many people who have benefited from tai chi. She has practiced tai chi for more than 10 years. For her, it's a way of life. Tai chi has taught her the value of "going slowly". She once felt great stress at work and in her life, but that began to change thanks to tai chi, which helped her "gain peace and inner harmony"， she said. "For me now, practicing tai chi is like speaking with my soul."

Clothing rental is a hot new industry and retailers are demanding to get on board in hopes of attracting green shoppers.

But is renting fashion actually more environmentally­friendly than buying it, and if so, how much more? Journalist and author Elizabeth Cline investigated this question and concluded that it's not as sustainable as it seems.

Take shipping, for example, which has to go two ways if an item is rented—receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.

She writes, "An item ordered online and then returned can send out 20 kilograms of carbon each way, and increases up to 50 kilograms for rush shipping. By comparison, the carbon impact of a pair of jeans purchased from a physical store and washed and worn at home is 33.4 kilograms, according to a 2015 study by Levi's."

Then there's the burden of washing, which has to happen for every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry cleaning, a high impact and polluting process. All the rental services that Cline looked into have replaced perchloroethylene, an air pollutant that causes cancers, still used by 70 percent of US dry cleaners, with alternatives, although these aren't great, either.

Lastly, Cline fears that rental services will increase our appetite for fast fashion, simply because it's so easily accessible. There's something called "share washing" that makes people waste more precisely because a product or service is shared and thus is regarded as more eco­friendly. Uber is one example of this, advertised as "a way to share rides and limit car ownership." and yet "it has been proven to discourage walking, bicycling, and public transportation use."

Renting clothes is still preferable to buying them cheap and throwing them in the dustbin after a few wears, but we shouldn't let the availability of these services make us too satisfied. There's an even better step—that's wearing what is already in the closet.

You probably already know that exercising is necessary to preserve muscle strength, keep your heart strong, and help you keep a healthy body weight. "There's a lot of science behind this，" says Dr. Scott McGinnis, an instructor at Harvard Medical School.

Exercise improves your memory and thinking skills both directly and indirectly. It acts directly on the brain by encouraging the growth of new blood vessels (血管) in the brain. Besides, many studies have suggested that the parts of the brain that control thinking and memory are larger in size in people who exercise than in people who don't.

Exercise can also improve memory and thinking skills indirectly. Problems in these areas frequently cause or contribute to memory loss and a lack of problem­solving skills.

Is one exercise better than another in terms of brain health? Almost all of the research so far has looked at walking."But it's likely that another form of exercise that gets your heart pumping might produce similar benefits，"explains Dr. McGinnis. A study found that tai chi showed the potential to help older adults in planning, working memory, attention and problem­solving. That may be because tai chi involves slow, focused movements and requires learning and memorizing new skills as well as movement patterns.

Dr. McGinnis recommends establishing exercise as a habit. Several studies have shown that it takes about six months to start getting the benefits of exercise.

A. We don't know the answer to this question.

B. It makes you more resistant to some diseases.

C. It even promotes the overall health of new brain cells.

D. It improves people's sleep and reduces their stress and anxiety.

E. Thus, he reminds you to be patient as you look for the first results.

F. But exercise can also help improve your memory and thinking skills.

G. Start with a few minutes a day and increase the amount until you reach your goal.
